to insure goods to send them overseas it costs the exporter 5/2% of the value of the goods. if the goods are valued at 16.400$, what will be the insurance cost?​

Answers

Answer:

The insurance costs to send goods valued at $16,400 is $410  

Step-by-step explanation:

The amount it costs an exporter to insure goods to send overseas = (5/2)% of the value of the goods

Therefore;

The insurance costs, 'C' to send goods valued at $16,400 is given as follows;

C = $16,400 × (5/2)/100 = $410

The insurance costs to send goods valued at $16,400 = $410

and the x has to be the same for each

Answers

Answer:

x = 5

Step-by-step explanation:

4x + 8 - 9x = -17

combine like terms:

-5x = -25

divide both sides of the equation by -5:

x = 5

Answer:

x=5

Step-by-step explanation:

4x-9x+8=-17

-5x+8=-17

subtract 8 from both sides and you get:

-5x=25

divide 5 from both sides, and you get x=5! :)

Brad read that you should drink at least 2 quarts of water a day. Yesterday he drank 3 cups in the morning, 1 quart in the afternoon, and 1 pint in the evening. Did Brad drink at least 2 quarts of water? Explain.

Step-by-step explanation:

with the two points, you could find the point-slope equation...

y−7.3=0⋅(x+4)

this is y=7.3

there is no slope-intercept equation for this because both of the points are on the same horizontal line. Equations that are written in slope-intercept form are never horizontal or vertical.

For the function, f(x) =1/4 x - 2, find x if f(x) = -1.

Answers

Answer:

x = 4

Step-by-step explanation:

Given function  

f(x) =1/4 x - 2

Find x if f(x) = -1

1/4x - 2 = - 11/4x = 2 - 11/4x = 1x = 1*4x = 4

Answer:

x=4

Step-by-step explanation:

f(x) =1/4 x - 2 when f(x) = -1.

-1=1/4x-2

-1+2=1/4 x

1×4=x

x=4

Robert takes out a loan for $7200 at a 4.3% rate for 2 years. What is the total paid amount at the end of the loan?

Answers

Answer:

$7819.20

Step-by-step explanation:

total paid amount at the end of the loan= loan taken + interest on the loan

loan taken = $7200

interest on the loan can be determined using this formula

Interest = principal x intrest rate x time

7200 x 0.043 x 2 = $619.20

total paid amount at the end of the loan= $7200 + $619.20 = $7819.20
